PROFESSIONAL EXPERIENCE

SLB

Disk Archive Coordinator 10/23/2023 – 5/29/2024

• Responsible for archiving seismic data using Omega software, including monitoring and troubleshooting any issues that arise.

• Communicate with Processing and Asset Development teams to monitor and schedule the transfer of data volumes.

• Create risk management tape copies.

• Produce status and resource requirement reports for management and interact with clients as needed

Katalyst Data Management

QC Technician 7/05/2023 – 10/22/2023

• Index and QC data and metadata using tools such as SeisSee, SegDSee, Neuralog, Excel, iGlass, and other software. Resolve errors or issues that may have been missed using these tools in both Windows and Unix environments.

• Run and correct transcription jobs, transferring client data to iGlass (the software used by clients) to search and view the final data.

• Research data to identify and prevent duplication according to client profiles.

• Update the Work Management Tool with comments and billing information for each job.

• Communicate with Account Managers, Computer Operators, and Indexers to resolve issues related to data integrity.

TGS

Senior Seismic Interpreter 3/16/2020 – 5/15/2023

• South Timbalier - Grand Isle South, Gulf of Mexico: Integrated data from over 100 wells to interpret complex sediment and salt movement for input to FWI. This area features steeply dipping salt welds that juxtapose slower shallow velocity sediment accumulations with underlying faster velocity sediments, such as Jurassic carbonates. Accurate interpretation of the shallow section improved subsalt imaging for prospectivity assessment.

• Offshore Brazil - Espirito Santo, Campos, Santos, and Pelotas Basins: Incorporated relevant well data to create detailed maps of sequence boundaries, carbonate sections, and salt to enhance imaging of the pre-salt section. All work was performed for input to FWI.

• Mississippi Canyon - Atwater Valley, Gulf of Mexico: Used relevant well information to interpret sediment and salt structures for multi-client and proprietary projects (FWI). Emphasized the interaction between canopy salt and compressional structures of the Atwater fold belt. Accurate interpretation of this interaction, which juxtaposes carbonate against canopy salt, improved imaging of the Cotton Valley formation in these areas.

• Offshore Liberia (West Africa): Interpreted regional 2D lines to identify major sequence boundaries, aiding in processing to enhance seismic velocity constraints and improve imaging.

Subsurface Consultants (consulting at TGS)

Senior Geophysical Interpreter 1/31/2017 – 11/23/2017 & 6/2019 – 3/15/2020

• Performed geophysical interpretation on multiple projects in the Gulf of Mexico, identifying sequence boundaries, unconformities, over-pressured shale, carbonate sequences, and salt bodies for TGS velocity model building input to FWI migration.

• Utilized well information (formation tops and curve interpretation), gathers, and basin research to constrain interpretations.

• Conducted scenario testing to enhance image quality in poorly imaged areas.

Petroleum Geo-Services

Senior Seismic Interpreter - Manager 07/2013 - 01/2016

• Trained staff on the general depositional history of the Gulf of Mexico and its impact on their work, enhancing project quality and reducing turnaround time.

• Applied geological and geophysical expertise to improve imaging on proprietary projects in the Gulf of Mexico, boosting PGS project revenue through repeat client business.

• Developed best practice guides for interpretation staff, specifically for esoteric VMB (Velocity Model Building) interpretation.

Petroleum Geo-Services

Senior Geophysical Interpreter - Supervisor 12/2012 - 07/2013

• Assisted Pemex in the southern Gulf of Mexico (Centauro project) and the Bay of Campeche by improving the imaging of AOIs through accurate seismic interpretation. Utilized my knowledge of depositional and structural histories to create plausible geological scenarios and tied interpretations to available well data.

• Tested overpressure theories by inserting varying (slower) seismic velocities into shale bodies and observing image improvements.

• Supervised the technical and managerial aspects of Houston projects, including resource management, Gantt chart creation, technical support, client liaison, and progress reporting.

INEXS

Senior Seismic Interpreter – Advisor 08/2008 - 12/2012

• Applied geological and geophysical expertise to create precise seismic interpretations for project work at GX & WesternGeco. Trained staff on various aspects of the Gulf of Mexico's depositional history, including faulting related to salt movement, distinguishing salt suture from base salt, identifying welds and unconformities through deeper seismic imaging, and understanding salt/sediment interactions in both extensional and compressional regimes. Additionally, used seismic gathers to support geologic interpretation.

• Conducted proprietary interpretation work across multiple protraction areas in the northern Gulf of Mexico for clients such as BP, Exxon, BHP, Noble, Nexen, Statoil, Cobalt, Marathon, Hess, and Woodside.

Veritas Hampson-Russell (CGGVeritas)

Senior Geophysicist / team lead 05/2001- 08/2008

• Responsible for project management, including workflow, personnel assignments, interpretation QC, and coordination with the processing team to ensure efficient progress. Presided over client technical meetings and maintained close contact with clients to ensure satisfaction.

• Interpreted salt for input into PSDM migration using available geological and geophysical data.

• Incorporated regional geological history to explain and constrain salt body development.

• Mapped slow velocity areas (shale bodies) in proximity to salt for input into PSDM.

• Mapped fast velocity carbonates above salt for input into PSDM.

Veritas Exploration Services

AVO Geophysicist 07/1998 – 05/2001

• Performed AVO/AVA analysis to obtain reflectivity attributes, including Shuey’s, Verm and Hilterman’s, Smith and Gidlow’s, Gidlow’s, and Grey’s attributes.

• Conducted well ties to seismic, well location phase analysis, and fluid substitution modeling.

• Executed shear wave birefringence analysis to determine fracture orientation and gain a better understanding of fluid migration.

• Performed P-wave analysis to identify over-pressure zones that may impact drill locations.

• Analyzed attribute cross-plots for anomalies indicating potential hydrocarbons.

Veritas Geophysical Services

Processing Geophysicist 11/1995 - 07/1998

• Performed post-stack time migration, including deconvolution, filtering, de-multiple, wavelet processing, velocity analysis, statics, and migration. Additionally, spent 6 weeks on an acquisition vessel, QC’ing data.
